Low-Cost Silicon Bipolar Design  
The MAX2410 performs the RF front-end transmit/receive  
function in time-division-duplex (TDD) communication  
systems. It operates over a wide frequency range and  
is op timize d for RF fre q ue nc ie s a round 1.9GHz.  
Applications include most popular cordless and PCS  
standards.  
Integrated Upconvert/Downconvert Function  
Operates from Single +2.7V to +5.5V Supply  
3.2dB Combined Receiver Noise Figure:  
2.4dB (LNA)  
9.8dB (Mixer)  
The MAX2410 contains a low-noise amplifier (LNA), a  
downconverter mixer, a local-oscillator (LO) buffer, an  
upconverter mixer, and a variable-gain power-amplifier  
(PA) driver in a low-cost, plastic surface-mount package.  
The LNA ha s a 2.4d B (typ ic a l) nois e fig ure a nd a  
-10dBm input third-order intercept point (IP3). The down-  
converter mixer has a low 9.8dB noise figure and a  
3.3dBm IP3. Image and LO filtering are implemented off-  
chip for maximum flexibility. The PA driver has 15dB of  
gain, which can be reduced over a 35dB (typical) range.  
Power consumption is only 60mW in receive mode or  
90mW in transmit mode and drops to less than 0.3µW in  
shutdown mode.  
Flexible Power-Amplifier Driver:  
18dBm Output Third-Order Intercept (OIP3)  
35dB Gain Control Range  
LO Buffer for Low LO Drive Level  
Low Power Consumption:  
60mW Receive  
90mW Full-Power Transmit  
0.3µW Shutdown Mode  
Flexible Power-Down Modes Compatible with  
MAX2510/MAX2511 IF Transceivers  
A similar part, the MAX2411A, features the same func-  
tiona lity a s the MAX2410 b ut offe rs a d iffe re ntia l  
bidirectional (transmit and receive) IF port. This allows  
the use of a single IF filter for transmit (TX) and receive  
(RX). For applications requiring a receive function only,  
consult the data sheet for the MAX2406, a low-cost  
downconverter with low-noise amplifier.
